Abstract: Spss is one of statanslysis softwares w hich is prevalent bo th in china and abroad. People have to compile the programs of cycle structure when they have to apply the symmetrical systematic sampling. But its structure doesn’t have the characteristic of cycle structure, so the paper is to analyze how the symmetrical systematic sampling is achieved in Spss, structure and then illustrates the practicability, the veracity, and the quality of the method with an example.

Key words: systematic sampling; spss softwares; cycle structure. 　CLC: F222. 1
